Description

Die Erfindung betrifft eine Spannvorrichtung zum Abziehen von Lagerringen von Radflanschnaben gemäß dem Oberbegriff des Hauptanspruchs.The invention relates to a tensioning device for removing bearing rings from wheel flange hubs according to the preamble of the main claim.

Derartige Vorrichtungen werden zum Abziehen von auf Radflanschnaben von Kraftfahrzeugen aufgepreßten Innenringen von Kugellagern benötigt und benutzt.Devices of this type are required and used to pull off inner rings of ball bearings pressed onto wheel flange hubs of motor vehicles.

Bei einer bekannten Vorrichtung dieser Art (siehe DE-C 829 129) sind die beiden aus im wesentlichen halbkreisförmigen Scheiben bestehenden Spannbacken durch zwei in diametraler Tangentiallage parallel zueinander verlaufenden Anordnung an den Spannbacken befestigte Gewindespindeln gegeneinander preßbar. Die beiden Spannbacken sind jeweils auf den einander zugekehrten Seite mit halbrunden Ausnehmungen versehen, welche stirnseitig am Bund des abzuziehenden Lagerringes mehr oder weniger passend angesetzt und verspannt werden können, wenn eine entsprechende Ringrille vorhanden ist. Zum eigentlichen Abziehen des Lagerringes wird ein zusätzliches Ziehwerkzeug benötigt, das zwei an einem Balken befestigte Gewindebolzen aufweist, die in Gewindebohrungen der beiden Spannbacken einschraubbar sind, wobei in der Mitte des Balkens eine Druckspindel angeordnet ist, mit der mit Hilfe eines Druckstückes die Flanschnabe in axialer Richtung aus dem Lagerring herausdrückt werden kann.In a known device of this type (see DE-C 829 129), the two clamping jaws, consisting essentially of semicircular disks, can be pressed against one another by two threaded spindles attached to the clamping jaws and running parallel to one another in a diametrical tangential position. The two jaws are each provided on the side facing each other with semicircular recesses, which can be more or less appropriately attached and braced on the end face of the collar of the bearing ring to be removed if a corresponding ring groove is present. For the actual removal of the bearing ring, an additional drawing tool is required, which has two threaded bolts attached to a beam, which can be screwed into the threaded bores of the two clamping jaws, a pressure spindle being arranged in the middle of the beam, with which the flange hub can be axially fixed with the help of a pressure piece Direction can be pushed out of the bearing ring.

Abgesehen davon, daß diese bekannte Vorrichtung nicht universell einsetzbar ist, weil ihre Spannbacken nur auf wenige der in der Praxis vorkommende Lagerringe passen, ist auch die hier zu verwendende Abziehvorrichtung insbesondere dann unbefriedigend, wenn sehr hohe Druckkräfte zum Herausdrücken der Lagernabe aus dem Lagerring aufgewendet werden müssen. Häufig ist mit den bekannten Vorrichtungen ein Lösen bzw. Abziehen des inneren Lagerringes eines Wälzlagers von der Hohlnabe eines Radflansches nicht möglich.Apart from the fact that this known device cannot be used universally because its clamping jaws only fit a few of the bearing rings that occur in practice, the pulling device to be used here is also unsatisfactory in particular when very high compressive forces are used to push the bearing hub out of the bearing ring have to. It is often not possible with the known devices to detach or pull off the inner bearing ring of a rolling bearing from the hollow hub of a wheel flange.

Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung der eingangs genannten Art derart zu verbessern, daß sie univer sell einsetzbar, leicht handhabbar, an unterschiedliche Lagerringe von Radflanschnaben ansetzbar und bedarfsweise sowohl mit einer mechanischen, eine Druckspindel aufweisenden Abziehvorrichtung, als auch auf pneumatischen, hydraulischen oder mechanischen Pressen verwendbar bzw. einsetzbar ist.The invention is based on the object of improving a device of the type mentioned in such a way that it can be used universally, is easy to handle, can be attached to different bearing rings of wheel flange hubs and, if necessary, both with a mechanical pulling device having a pressure spindle and on pneumatic, hydraulic or mechanical presses can be used or used.

Gelöst wird diese Aufgabe nach der Erfindung durch die Merkmale des kennzeichnenden Teils des hauptanspruchs.This object is achieved according to the invention by the features of the characterizing part of the main claim.

Durch die flache Bauweise ist die Vorrichtung nicht nur leicht handbar und platzsparend aufgebaut, sondern sie bietet auch den Vorteil, daß das Ansetzen der Spannbacken an dem abzuziehenden Lagerring ebenso gut einsehbar und damit kontrollierbar ist, wie der Abziehvorgang selbst. Ein weiterer wichtiger Vorteil der durch diese Bauform erzielt wird, besteht darin, daß die gesamte Vorrichtung mit einem eingespannten, noch auf der Lagernabe einer Radflanschnabe sitzenden Lagerring leicht auf den Arbeitstisch einer pneumatischen, hydraulischen oder mechanischen Presse gesetzt werden kann, um die Radflanschnabe nach unten herauszudrücken.Due to the flat design, the device is not only easy to handle and space-saving, but it also has the advantage that the attachment of the clamping jaws on the bearing ring to be removed can be seen and controlled as easily as the removal process itself. Another important advantage of the this design is achieved, is that the entire device with a clamped, still on the bearing hub of a wheel flange hub bearing ring can be easily placed on the work table of a pneumatic, hydraulic or mechanical press to push the wheel flange hub down.

Anhand der Zeichnung wird im folgenden ein Ausführungsbeispiel der Erfindung näher erläutert. Es zeigt:

  • Fig. 1 in perspektivischer Explosionsdarstellung die erfindungsgemäße Spannvorrichtung mit auswechselbaren Spannschalen, einer Abziehglocke und einer Radflanschnabe mit einem abzuziehenden Lagerring;
  • Fig. 2 die erfindungsgemäße Spannvorrichtung im Schnitt mit einem auf einer Radflanschnabe sitzenden, eingespannten Lagerring und mit aufgesetzter Ziehglocke;
  • Fig. 3 im Schnitt die auf zwei Distanzklötzen eines Pressentisches aufsitzende Spannvorrichtung mit eingespanntem Lagerring und stirnseitig von oben auf die Radflanschnabe einwirkenden Preßstempel.
An exemplary embodiment of the invention is explained in more detail below with reference to the drawing. It shows:
  • Figure 1 is a perspective exploded view of the clamping device according to the invention with interchangeable clamping shells, a pull bell and a wheel flange hub with a bearing ring to be removed.
  • 2 shows the clamping device according to the invention in section with a clamped bearing ring seated on a wheel flange hub and with a pull bell attached;
  • Fig. 3 in section, the clamping device seated on two spacer blocks of a press table with a clamped bearing ring and press ram acting on the end of the wheel flange hub from above.

Die erfindungsgemäße Spannvorrichtung 1 zum Abziehen von Lagerringen 2 von Radflanschnaben 3 besteht aus zwei Spannbacken 4 und 5, die zwischen zwei parallel zueinander verlaufenden Längsschenkeln 6 und 7 angeordnet, welche am einen Ende durch einen Querschenkel 8 miteinander verbunden sind. Auf ihren einander zugekehrten Innenseiten weisen die Längsschenkel jeweils federartige Führungsrippen 9 bzw. 10 auf, welche formschlüssig in entsprechend profilierte seitliche Längsnuten 11 bzw. 12 bzw. 13 und 14 der beiden Spannbacken 4 und 5 formschlüssig eingreifen. Auch der Querschenkel 8 ist beidseitig mit Nuten 8' versehen, in welche die Führungsrippen 9 und 10 der beiden Längsschenkel 6, 7 formschlüssig eingreifen, und zur Versteifung des Spannrahmens beitragen. Während die Spannbacke 4 mit den beiden Längsschenkeln 6 und 7 durch querverlaufende Schrauben 16 verschraubt und somit fest mit ihnen verbindung ist, ist die Spannbacke 5 auf den Führungsrippen 9 und 10 zwischen der Spannbacke 4 einerseits und dem Querschenkel 8, der ebenfalls am anderen Ende mit den beiden Längsschenkeln 6 und 7 durch Schrauben 16 verschraubt ist, um etwa 30 mm in Längsrichtung hin und her schiebbar. Es ist aus Fig. 1 erkennbar, daß die beiden Spannbacken 5 und 6 jeweils aus gleich dicken, flachen, plattenartigen Körpern bestehen und daß sowohl die beiden Längsschenkel 6 und 7 als auch der Querschenkel 8 die gleiche Dicke wie die Spannplatten 4 und 5 aufweisen, sodaß ihre flachseitigen Oberflächen jeweils in einer gemeinsamen Ebene liegen. An den einander zugekehrten Seiten sind die beiden Spannbacken 4 und 5 jeweils mit halbrunden Ausnehmungen 17 bzw. 18 versehen, die jeweils eine halbkreisförmige, im Querschnitt rechteckige bzw. quadratische, federartige Randrippe 19 bzw. 20 aufweisen, welche zur formschlüssigen Aufnahme unterschiedlicher, auf die äußere Form unterschiedlicher Lagerringe abgestimmte Spannschalen 21 und 22 bzw. 23 dienen.The clamping device 1 according to the invention for removing bearing rings 2 from wheel flange hubs 3 consists of two clamping jaws 4 and 5, which are arranged between two parallel longitudinal legs 6 and 7, which are connected at one end by a cross leg 8. On their mutually facing inner sides, the longitudinal legs each have spring-like guide ribs 9 or 10, which positively engage in correspondingly profiled lateral longitudinal grooves 11 or 12 or 13 and 14 of the two clamping jaws 4 and 5. The transverse leg 8 is also provided on both sides with grooves 8 ', into which the guide ribs 9 and 10 of the two longitudinal legs 6, 7 engage in a form-fitting manner and contribute to stiffening the tenter frame. While the clamping jaw 4 is screwed to the two longitudinal legs 6 and 7 by transverse screws 16 and is thus firmly connected to them, the clamping jaw 5 is on the guide ribs 9 and 10 between the clamping jaw 4 on the one hand and the cross leg 8, which is also at the other end the two longitudinal legs 6 and 7 is screwed by screws 16, about 30 mm in the longitudinal direction back and forth. 1 that the two clamping jaws 5 and 6 each consist of flat, plate-like bodies of the same thickness and that both the longitudinal legs 6 and 7 and the transverse leg 8 have the same thickness as the clamping plates 4 and 5, so that their flat surfaces are each in a common plane. On the mutually facing sides, the two jaws 4 and 5 are each provided with semicircular recesses 17 and 18, each of which has a semicircular, rectangular or square in cross-section, spring-like edge rib 19 or 20, which for the positive reception different on the Outer shape of different bearing rings matched clamping shells 21 and 22 and 23 serve.

Die Längsverschiebung der Spannbacke 5 geschieht durch das Drehen einer Gewindespindel 24, die in einer Gewindebohrung 25 des Querschenkels 8 sitzt und deren vorderes Ende mittels eines O-Ringes 26 in einer stirnseitigen Sackbohrung 27 der Spannbacke 5 drehbar befestigt ist. Um auf die Gewindespindel 24 eine großes Drehmoment ausüben zu können, ist diese an ihrem freien Ende mit einem Knebel 28 versehen.The longitudinal displacement of the jaw 5 is done by rotating a threaded spindle 24, which is in a threaded bore 25 of the cross leg 8 sits and the front end of which is rotatably fastened by means of an O-ring 26 in an end blind bore 27 of the clamping jaw 5. In order to be able to exert a large torque on the threaded spindle 24, this is provided with a toggle 28 at its free end.

Wie ebenfalls aus Fig. 1 ersichtlich ist, sind die beiden als halbkreisförmige Körper ausgebildeten Spannschalen 21 und 22 sowie auch die Spannschalen 23 und 23' aus Fig. 2 an ihrem Umfang jeweils mit einer Ringnut 29 versehen, welche im Profil so geformt ist, daß sie eine der Randrippen 19 bzw. 20 der beiden Spannbacken 4 oder 5 formschlüssig, jedoch mit einem gewissen radialen Spiel, das eine exakte Zentrierung am Lagerring 2 ermöglicht, aufnehmen kann.As can also be seen from FIG. 1, the two clamping shells 21 and 22 designed as semicircular bodies and also the clamping shells 23 and 23 'from FIG. 2 are each provided on their circumference with an annular groove 29 which is shaped in profile in such a way that it can receive one of the edge ribs 19 or 20 of the two clamping jaws 4 or 5 in a form-fitting manner, but with a certain radial play, which enables exact centering on the bearing ring 2.

Während die beiden Spannschalen 21 und 22 auf ihrer Innenseite jeweils mit einer im Profil halbkreisförmigen, nach innen vorspringenden Ringrippe 30 versehen ist, weisen die Spannschale 23 und 23' an ihren Unterkanten eine nach innen vorspringende Greifernase 31 auf, welche in entsprechenden Ausnehmungen 32 (Fig. 2) einer Radflanschnabe 3 den abzuziehenden Lagerring 2 stirnseitig hintergreifen können, wie es in Fig. 2 dargestellt ist. Für Lagerringe 2, die an ihrem Umfang eine Kugel-Laufrille 2' aufweisen, werden Spannschalen 21 und 22 in der Spannvorrichtung 1 fest eingespannt, welche auf ihren Innenseiten entsprechend profilierte Ringrippen 30 aufweisen, wie das in Fig. 3 dargestellt ist. Zum Herausdrücken der Radflanschnabe aus dem nach Fig. 2 oder 3 in die Spannvorrichtung 1 eingespannten Laggerring 2 kann entweder, wie in Fig. 2 dargestellt ist, eine Abziehglocke 33 verwendet werden, die einen Spannflansch 34 mit Durchstecköffnungen 36 bzw. 37 aufweist und mittels Schrauben 38, die in Gewindebohrungen 39 der beiden Spannbacken 4 und 5 oder Gewindebohrungen 40 der beiden Längsschenkel 6 und 7 einschraubbar sind, auf der Oberseite der Spannvorrichtung 1 befestigt werden kann. Mittels einer Druckspindel 41, die mit Hilfe eines Knebels 42 drehbar in einer zentralen Gewindebohrung 43 des Halses der Abziehglocke sitzt, kann mittels eines auf die Stirnseite der Hohlnabe 44 aufgesetzten Druckstückes 45 die Radflanschnabe 3 aus dem Lagerring 2 herausgedrückt werden. Dabei ist es zweckmäßig, die Spannvorrichtung 1 beispielsweise in einen Schraubstock einzuspannen, um an der Gewindespindel 41 das nötige Drehmoment leichter aufbringen zu können.While the two clamping shells 21 and 22 are each provided on their inside with a semicircular profile, inwardly projecting ring rib 30, the clamping shells 23 and 23 'have an inwardly projecting gripper nose 31 on their lower edges, which in corresponding recesses 32 (Fig 2) a wheel flange hub 3 can engage behind the bearing ring 2 to be removed, as shown in FIG. 2. For bearing rings 2, which have a ball groove 2 'on their circumference, clamping shells 21 and 22 are firmly clamped in the clamping device 1, which have correspondingly profiled ring ribs 30 on their inner sides, as shown in FIG. 3. To push the wheel flange hub out of the Laggerring 2 clamped in the tensioning device 1 according to FIG. 2 or 3, either a pull-out bell 33 can be used, as shown in FIG. 2, which has a clamping flange 34 with push-through openings 36 or 37 and by means of screws 38, which can be screwed into threaded holes 39 of the two clamping jaws 4 and 5 or threaded holes 40 of the two longitudinal legs 6 and 7, can be fastened on the upper side of the clamping device 1. The wheel flange hub 3 can be pressed out of the bearing ring 2 by means of a pressure spindle 41, which is rotatably seated in a central threaded bore 43 of the neck of the pull-off bell by means of a toggle 42, by means of a pressure piece 45 placed on the end face of the hollow hub 44. It is expedient to clamp the clamping device 1, for example in a vice, in order to be able to apply the necessary torque more easily to the threaded spindle 41.

Es ist aus Fig. 1 erkennbar, daß zum Durchstecken der Schrauben 38 der Ringflansch 34 mit Langlöchern 36 bzw. 37 versehen ist, damit eine Zentrierung der Abziehglocke 33 zu der eingespannten Radflanschnabe 2 möglich ist.It can be seen from FIG. 1 that the annular flange 34 is provided with elongated holes 36 and 37 for pushing through the screws 38 so that centering of the pull bell 33 to the clamped wheel flange hub 2 is possible.

Wenn eine Abziehglocke oder ähnliche Abziehvorrichtung, bei spielsweise eine Abziehbrücke, nicht zu Verfügung steht oder die zum Herauspressen der Hohlnabe 44 aus dem eingespannten Lagerring 2 erforderlichen Druckkräfte mit der Druckspindel 41 nicht aufgebracht werden können, besteht auch die Möglichkeit nach Fig. 3, die Spannvorrichtung 1 mit Hilfe zweier Distanzklötze 50 und 51 auf den Preßtisch 52 einer weiter nicht dar gestellten Presse beliebiger Bauart und Funktionsweise zu setzen und das Herausdrücken der Hohlnabe 44 aus dem Lagerring 2 mit dem Preßstempel 53 unter Benutzung eines passenden Druckstückes 54 zu bewerkstelligen. Es versteht sich, daß man mit einer beispielsweise hydraulisch oder pneumatisch betätigten oder aber mit einer Exzenterpresse, die mehrere Tonnen Preßdruck aufzubringen in der Lage ist, den Abziehvorgang leichter durchführen kann, als mit einer Abziehglocke. 33 oder einem ähnlichen Abziehgerät.If a pull-off bell or similar pull-off device, for example a pull-off bridge, is not available or the pressure forces required to press the hollow hub 44 out of the clamped bearing ring 2 cannot be applied with the pressure spindle 41, there is also the possibility according to FIG. 3, the clamping device 1 with the help of two spacer blocks 50 and 51 on the press table 52 of a press, not shown, of any design and mode of operation and to push out the hollow hub 44 from the bearing ring 2 with the press ram 53 using a suitable pressure piece 54. It goes without saying that with a hydraulically or pneumatically operated or with an eccentric press, which is able to apply several tons of pressure, the removal process can be carried out more easily than with a removal bell. 33 or a similar puller.

Damit die beiden Distanzklötze 50 und 51, durch welche die erforderliche Hubfreiheit zwischen der unteren Stirnseite der Radflanschnabe 3 und dem Preßtisch 52 hergestellt werden soll, an der Unterseite der Spannvorrichtung 1 gut anliegen, ist die Spannvorrichtung 1 so gestaltet, daß die Oberflächen sowohl der Spannbacken 4 und 5 als auch der einen Spannrahmen bildenden Längsschenkel 6 und 7 jeweils glatte Ebenen bilden. Außerdem ist zumindest die Länge oder die Breite der Spannvorrichtung 1 so groß gewählt, daß sie den größtmöglichen Durchmesser einer Radflanschnabe 3 um wenigstens 4 cm überragt, damit die beiden erforderlichen Distanzklötze 50 und 51 außerhalb der Radflanschnabe untergesetzt werden können.So that the two spacer blocks 50 and 51, by means of which the required freedom of stroke is to be produced between the lower end face of the wheel flange hub 3 and the press table 52, lie well against the underside of the clamping device 1, the clamping device 1 is designed such that the surfaces of both the clamping jaws 4 and 5 as well as the longitudinal legs 6 and 7 forming a clamping frame each form smooth planes. In addition, at least the length or the width of the tensioning device 1 is chosen so large that it projects beyond the largest possible diameter of a wheel flange hub 3 by at least 4 cm, so that the two required spacer blocks 50 and 51 can be placed outside the wheel flange hub.

Es ist aus den Fig. 2 und 3 erkennbar, daß der Abziehvorgang im einen wie im anderen Fall von oben gut zu beobachten ist. Für unterschiedliche Lagerringe 2 stehen, wie bereits erwähnt, unterschiedliche angepaßte Spannschalen 21, 22 und 23, 23' zur Verfügung, so daß die Spannvorrichtung 1 universell einsetzbar ist. Durch die massive und flache Bauweise hat die rahmenartige Konstruktion eine sehr hohe Festigkeit, so daß hohe Druckkräfte sowohl in Spannrichtung als auch in Abziehrichtung aufgenommen bzw. aufgebracht werden können, wobei jederzeit die Möglichkeit besteht, durch entsprechende Drehung der Gewindespindel 24 die Druckspannung, mit welcher die abzuziehenden Lagerringe in die Vorrichtung eingespannt werden, zu erhöhen.It can be seen from FIGS. 2 and 3 that the pull-off process can be easily observed from above in one case as in the other. As already mentioned, different adapted clamping shells 21, 22 and 23, 23 'are available for different bearing rings 2, so that the clamping device 1 can be used universally. Due to the solid and flat design, the frame-like construction has a very high strength, so that high compressive forces can be absorbed or applied both in the clamping direction and in the pulling direction, with the possibility at any time, by appropriate rotation of the threaded spindle 24, the compressive stress with which the bearing rings to be removed are clamped in the device to increase.
